记录一下 搭建springboot，springCloud，springCloudAlibaba，nacos

1，首先创建一个空项目 里面 有两个服务 一个提供者 一个调用者

 2，父工程的使用依赖  以及springBoot的父依赖

    // springboot父工程
    <parent>
        <artifactId>spring-boot-starter-parent</artifactId>
        <groupId>org.springframework.boot</groupId>
        <version>2.3.12.RELEASE</version>
    </parent>

    <groupId>com.yh</groupId>
    <artifactId>day0804</artifactId>
    <packaging>pom</packaging>
    <version>1.0-SNAPSHOT</version>
    <modules>
        <module>day_user</module>
        <module>day_application</module>
    </modules>

    <name>day0804</name>
    <!-- FIXME change it to the project's website -->
    <url>http://www.example.com</url>
    // 一些配置信息和版本
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>1.8</java.version>
        <!--        三个框架版本-->
        <org.boot.service>2.3.12.RELEASE</org.boot.service>
        <org.cloud.service>Hoxton.SR12</org.cloud.service>
        <org.cloudali.service>2.2.7.RELEASE</org.cloudali.service>
        <!--        lombok版本-->
        <org.lombok.version>1.18.20</org.lombok.version>
    </properties>

    <dependencyManagement>
        <dependencies>
            <!--      boot依赖-->
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${org.boot.service}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <!--      cloud依赖-->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${org.cloud.service}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <!--      alibaba依赖-->
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba-dependencies</artifactId>
                <version>${org.cloudali.service}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

然后在服务提供者（day_user_service）引用依赖

简单配置就这些 根据需求不断地增加迭代 不过是要注意版本之间的兼容性
